To all whom it may concern:

Be it known that I ,JALBEnr PErERsoN, a

' citizen of the United States, residin at Cambridge,'in the county ofHenry an State of Illinois, have invented certain new and. use ful Imrovements in Carbureters, of which the 0 owing is a specification.

This invention involves improvements. in that class of gas-machinesutilized particularly for generating as to be used for lightin cooking,or simi ar purposes.

he invention aims to provide a carburetor of simplified construction thevarious parts of which are arranged in such a manner as to be readilyaccessible for purposes of adjustment, repair, or the like, the machinebeing designed to generate a maximum amount of gas with a minimumquantity of air used in the generation of such gas.

A further object of the lnvention is to provide a carbureter of the typeinvolving the use of-a generator adapted to receive a quantity of liquidcarbon, such as gasolene, a supply-tank, and valve means governing t esupply of the liquid carbon to the generator in which the regulatingmeans for operatin the valve means will-feed positively and wi notpermit leaka e, which ordinarily causes the generation oavariable gaswith disadvantages of obvious import.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreifecting the result reference is to be had to the following descriptionand accompanying drawings, in which-' F1gure 1' is. a vertical sectionalview of a gas-machine or carbureter embodying the invention. Fi 2 is ahorizontal sectional view on the hne Y Y of Fig. 1 looking downwardly.Fig. 3 is a view similar to Fig. 2, taken on the line X X of Fig. 1.

Corresponding and. like, parts are referred to in the followindescription and indicated in all the views 0% the drawings by the sameSpecifically describing the invention, the

numeral 1 1n the drawings represents the generating or carburetingreceptacle or tank, above which, and preferably lorming a part of thegeneral structure of the tank 1, is located a supply-tank 2, in which-'the liquid carbon, which is preferably gasolene in this instance,

is placed in quantity The arangeme'nt of the generator land the tank 2conducive to compactnessin a manner readily apparent. The enerator 1receives a certain uantity of gaso ene, which is at the bottom 0 thereceptacle and several inches in de th.. Arranged in the generator 1 isa circu atin -plate 3- of approximately circular form, sai plate 3 beinsubmerged in fihe body of the asolene in t e generator, so t at airpassing t ough an inlet or air pipe 4 into the generator, said ipepassing throu h the plate 3 about centra ythereof, will be orced throughthe gasolene at the base of the enerator to be thoroughly mixedtherewitto eifect vaporizationand generation of the gas. The air-pipe 4, whichpasses through the plate 3, is rigidly attached to said late, havmg sealconnection. therewith, as s own at 5,

and this pipe extends upwardly from the plate 3.through a pipe 6 oflarger diameter connecting w1th a main air-pipe 7, leading from theair-pumps, which are ordinarily in the basement of the house orco'nvenientli located otherwise. The pipe 6, throug which the air-pipe 4passes, is a gasipe which leads through the top of the ta 2,

terminating at its lower end at the bottom of said tank in communicationwith the generating-chamber below. The pipe 6 likewise 'oins a maingas-pipe 8, lea 'ng off to the urners in the dwellmg or to any othersuitable point of utilization. It will be understood that inthepractical use of the inven-, tion the apparatus is commonly buried inthe. earth some distance from the dwelling, which is to be supplied withgas thereby, the pipes 7 and 8 likewise being beneath the surface of theound below the frost-line.

erably, the air-pipe 4 passing through the union in an obvious manner.filling-pipe 10 is provided" for the tank -2, said pipe extendinpreferably, from its upper extremity an provided with a suitable cap 11.The generator 1 is supplied with the hydrocarbon in the tank 2 by meansof the supplyipe 12, which extends vertically through the mttom of thetank 2 to the top thereof, having a cap The pipe 8 l is joined with thepipe 6 by a T-union 9, pref- 13 at its upper extremity. An inlet-opening14 affords communication between-the ortion of the pipe 12 below thebottom 2 o the tank 2 and the interior of said tank, the gasolene beingadapted to pass through the open-- ing 14 into the pipe 12 and outthelower end of this pipe 12 said lower end terminating at a point justabove the plate 3 in the'generator 1.

The lower ehd of the pipe 12 is normally closed by means of a valve 15,a nozzle 16 pro'ecting downwardly from the casing of sai valve andhaving its lower end portion normally submerged in the gasolene orhydrocarbon in the generator 1 for reasons which will appear more fullyhereinafter.

VI The valve is operated by a lever 17, fulcrumed upon the upper side ofthe late 3, as shown at 18, this lever having a oat 19 at one endoperated by the variation in the quantity of the gasolene in thegenerator, the opposite end of the lever 17 having an exten sion 20,projecting upwardly from the nozzle 16 and adapted to engage the valve15, so as to raise the latter in opening the same. The float 19 is ofthe usual hollow form, being of'approximately circular. construction,and upon the upper side of said'float is an engaging-'member in the formof a loop 21. The loop 21 is arranged'below the lower extremity of atube 22, which passes through the bottom 2'? to the top of the tank 2,said tube having a cap 23 at its upper extremity. The tube 22 is of asize admitting of passage of a rod or like device therethrough, so as toengage said rod with the loop or engaging member 21 of the float 19 toactuate this float in the event'the latter does not operate freely inits cooperation with the valve 15. The tube 22 is not only utilized as ameans for having access to the member 21 for the purpose abovementioned, but said tube will admit of initially filling the generatorwith the hydro-' carbon pre aratory to first using the ma chine, if itbe desired to pour the hydrocarbon through the tube in thegenerating-chamber.

Describing the operation and advantages of the apparatus hereinbeforeset forth, it will be noted that the arrangement of the plate 3 in thegenerator 1 is such that the quantity of gasolene or hydrocarbon thereinmay be comparatively small, so that air may be forced through the bodyof the liquid carbon without a great amount of pressure, as is necessaryin the majority of machines of this class. The passes from the pie 4through the body of the gasolene beneat the plate 3 and thence outwardlyfrom the center of the plate and upwardly into the body of the generator1, the outer peripheral portions of the plate 3 being of course spacedfrom the sides of-the generator to permit the air to take-the courseabove indicated. The gas is generated in the chamber of the generator 1in the manner above described and passes from the generator through thepipes 6 and S to the dwelling or points of utilization. When the levelof the gasolene in the generator 1 lowers, the float .19 of course movesdownwardly, raising the extension 20 and opening the valve 15, accordingto the degree of movement of the float. Opening of the valve 15 permitsthe gasolene in the supply-tank 2 to pass into the generator, saidgasolene enterin the pipe 12 through the openin 14. When the normallevel of the gasolene iii the generator 1 has been restored, the float19,-

moving upwardly, disengages the extension 20 from the valve, permittingthe latter to close by gravity, cutting off the inflowing gasolene inthe pipe 12. The provision of the nozzle 16 at the lower extremity ofthe pipe 12 is important in securin proper feeding of the gasolene andaction 0 the valve 15, since the submerged nozzle prevents the pressurein the generator- 1 from entering the pipe 12 and forcing the valveupwardly, causing the same to leak or otherwise affect its operation.Further, the passage of the gasolene through the pipe 12 into thegenerator 1 tends to createa vacuum in the tank 2, so that when thevalve 15 is closed, there being virtually no air-pressure in the tank 2and no the generator lowers to a point where the nozzle 16 is no longersubmerged the extension 20 will of course have been raised to actuatethe valve, as before described, and the air in the generator 1 ispermitted to pass up through the pipe 12 into the'tank 2, so that thegasolene in said tank may be freely supplied to the generator when thevalve is open.

.The plate 3 is preferably made of metal, and

said plate rests upon a plurality of hollow supports, referablyconsisting -of V-shaped ribs 3, w ich space the same from the bottom ofthe generator 1 and which are arranged radially of the plate, as shownmost clearly in the drawings. It will be obvious that it is designedthat the normal level of the hydrocarbon in the generator 1 be somedistance above the plate 3, for if said level becomes lower than saidplate it is clear that the air passing through the pipe 4 into thegenerating-chamber will be forced through the pipe 6 and out ofthegenerator without accomplishing the generation of the gas.

The provision of the pipe 12 in the construction shown is advantageous,in that the cap 13 may be moved and direct access may be had directly tothe valve 15 and the interior of the pipe in the event the latterbecomes clogged or it is desired to reach the valve and its casing.

'Having thus described the invention, what is'claimed as new isv In acarbureter, the combination of superposed reservoir or generatingtank's, a plate located within the generating-tank and spaced a shortdistance from the bottom t ereof,hollowsupports for said plate restinupon the bottom of the generating-tank an havin a radial arrangement, apipe passing centra 1y through the reservoir and generating-tank andconnecting with the centerjof said plate, a second pipe concentric withthe -first-mentioned. pipe and communicating with the upper portion ofthe generatingtank and passing throu h the reservoir-tank, a feed-pi eextended t ough the reservoirtank an passing into the generating-tankand having a nozzle at its lower end and a valve-easing above saidnozzle and provided witha feed-o em'ng above the bottom of thereservoir-ta ver having an engaging portion at its float end, and a pipe22 extending through the reservoir-tank and aboutin line Withtheengaging element of the float-controlled lever, the l upper ends of the(pipe 22 and the said feedpipe being adapte to be closed.
